c++ - 我正在尝试从类中的 boolean 值返回字符串，并始终返回true

我有一个打印出正方形行的构造函数。如果布尔值为true，则将其打印为填充，如果布尔值为false，则将其打印为空心。这项工作。但是= *（我还有另一个函数说是否空心或填充。它始终打印填充.....

Box::Box(int _width, int _height, bool filled)
{
if (filled)
{
    for (int i = 0; i < _height; i++)
    {
        cout << "x";
        for (int j = 1; j < _width; j++)
        {
            cout << "x";
        }
        cout << std::endl;
    }
}
else if (!filled);
{
    for (int i = 0; i < _height; i++)
    {
        if (i != 0 && i != _height - 1)
        {
            cout << "x";
            for (int j = 1; j < _width-1; j++)
            {
                cout << " ";
            }
            cout << "x";
        }
        else
        {
            for (int _longrow = 0; _longrow < _width; _longrow++)
            {
                cout << "x";

            }
        }
        cout << std::endl;
       }
    }
}

string Box::type() const
{
 if (filled)
 {
    return "Filled";
 }
 else if (!filled)
 {
    return "Hollow";
 }
}

最佳答案

Box::Box(int _width, int _height, bool afilled)
{
mfilled = afilled;
if (mfilled)
